GARBAGE BAG HOLDER Filed sept. 18, 1964 INVENTOR ERHAR KL/EwE/Z Wvo iHmfzy wAsvL vf PATENT AGENTS United States Patent O 3,260,488 GARBAGEBAG HOLDER Gerhard Kliewer and Harry Wasylyk, Winnipeg, Manitoba,Canada, assignors to Union Carbide Canada Limited, Toronto, Ontario,Canada, a company of Canada Filed Sept. 18, 1964, Ser. No. 397,439Claims. (Cl. 248-99) This invention relates to a holder for garbage bagsand the like. More particularly, this invention relates to a collapsibleholder for garbage bags and the like.

Collapsible garbage bag holders are known in the art, but, generallyspeaking, possess a number of disadvantages. Thus, some prior art typesof garbage bag holders are arranged so that the collapsible farmsthereof fold outwardly away from each other when the holder is-collapsed rather than folding inwardly towards each other. Such garbagebag holders suffer from the disadvantage that the overall width of theholder is greater in the collapsed position than in the uncollapsedposition thereof. In addition, in some cases the tendency may `be for agarbage bag held by such a holder to collapse in the same way as thearms of the holder, i.e., with the sides of the bag folding outwardlyaway from each other rather than inwardly towards each other. A bag soclosed has only two surfaces abutting each other at the closed end ofthe bag, whereas, if the sides of the bag folded inwardly towards eachother, there would be four 4bag surfaces abutting each other at theclosed end of the bag.

Other types of collapsible garbage bag holders make no provision forsecuring the holder in a closed position as by means of a lid. Stillother types of prior art garbage bag holders support the garbage bag -atonly the four corners thereof and do not provide adequate support forthe side walls of the -bag between the front and back walls thereof.

Accordingly, it is an object of this invention to provide a collapsiblegarbage `bag holder designed in such a manner that the collapsible armsof the frame thereof collapse inwardly towards each other, therebyrequiring the side walls of the bag held by the holder to similarlycollapse inwardly upon each other and also thereby causing the holder tobe of the same width in the collapsed or uncollapsed positions.

It is an object of a preferred embodiment of this invention to provide aholder for garbage bags and the like of the type mentioned in thepreceding paragraph which is provided with a lid which serves to firmlymaintain the garbage bag holder in a closed position.

Another object of a preferred embodiment of this invention is theprovision of a garbage bag holder as aforementioned which is providedwith means to directly support the side walls of a garbage bag or thelike.

In accordance with this invention there is provided a collapsible holderfor garbage bags and the like which comprises frame means and supportmeans for supporting the frame means, the support means includingmounting means for mounting the support means on a wall, door or thelike. The frame means comprise first, second and third arms. First hingemeans are provided to hingedly connect the first and third arms to thesupport means at spaced-apart points. Second hinge means are provided tohingedly connect the second arm to the first and third arms. rThirdhinge means are provided in each of the first and third armsintermediate the first and second hinge means for hinging the first andthird arms to collapse upon themselves during movement of the second armtowards the support means. Means are provided for constraining the firstand third `arms to collapse inwardly towards each other about the thirdhinge means when the second arm is furthest from the support me-ans iceand is moved towards the support means. Means are provided dependingfrom the holder for securing a garbage ybag or the like thereto.

This invention will become more apparent from the following detaileddisclosure taken in -conjunction with the appended drawings, in which:

FIGURE l is a perspective view of a holder embodying this invention inits fully opened position;

FIGURE 2 is a section taken along line 2-2 in FIG- URE l;

FIGURE 3 is a front elevation of the holder of FIG- URE 1 showing agarbage bag held thereby; and

FIGURE 4 is a perspective View of the holder of FIGURE l in fully closedposition.

Referring now to the drawings, there is shown a collapsible holder 10which consists of a frame 11 .and a support 12.

Support 12 consists of an elongated bar 13 to which is secured agenerally Z-shaped bracket 14 by any suitable means such as welding, forexample. Bracket 14- constitutes a mounting device for mounting support12 on a wall, door or the like 15, and to this end, bracket 14 has smallholes therein in which mounting screws 16 yare located.

Hingedly connected to support 12, and, more specifically, to bar 13, bymeans of hinges 17 is a lid 18 which is of generally U-shapedconfiguration and defines a channel 19 therein. Lid 18 has a front wall20, a back wal-l 21 and a top wall 22. Projecting forwardly from frontwall 20 is a tab or ange 23 whi-ch is designed to facilitate openingandclosing of the lid.

Frame 11 is formed from three arms 24, 25 and 26, each of arms 24 and 26consisting of two parts 24a, 24b and 26a, 26b respectively.

Arms 24 and 26, more specifically the ends of parts 2417 and 26brespectively thereof, are hingedly connected to bar 13 at spaced-apartpoints by hinges 27. Arms 24 and 26, more specifically the ends of parts24a and 26a respectively thereof, are hingedly connected to the ends ofarm 25 by hinges 28. In each of arms 24 and 26 a hinge 29 is providedand separates the two parts making up each arm. Preferably hinge 29 ispositioned one-half-way between hinges 27 and 2S.

The construction of hinges 29 is best seen in FIGURE 2 where it can beseen that each part 24a and 24b of arm 24 is provided with a hingeknuckle Si) through which a hinge pin 31 is inserted. A part 32 of thehinge knuckle 30 of part 2417 of arm 24 is cut out of the hinge knuckleand bent away therefrom to form a tab. As best seen in FIGURE 2, butalso apparent in FIGURE 1, tab 32 abuts against part 24a when the holderis in its fully opened position. Tab 32 therefore serves as a stop. Itwill be understood that hinge 29 between parts 26a and 2611 of arm 26 isconstructed with a tab 32 which abuts against part 26a when the holderis in its fully opened position. The effect of tabs 32 is to prevent thetwo parts of arms 24 and 26 from coming into 180 alignment with eachother when the holder is opened to its fully opened position. Thus, whenthe holder is collapsed by pushing arm 25 towards support 12 in thedirection indicated by the arrows in FIGURE 1, arms 24 and 26 not onlyare obliged to collapse in such a manner that the parts of `therespective arms -collapse upon each other, but also in such a mannerthat the arms collapse inwardly towards each other, as shown by thearrows in FIGURE l. In this connection, it should be appreciated thatarms 24 and 26 preferably are of the same length, and arm 25 preferablyis of the same length as 'bar 13.

As best shown in FIGURE 1, pins 33 are formed by the extensions of thevarious hinge pins of hinges 27, 28 and 29. These pins 33 serve as themeans for securing a garbage bag 34 (FIGURE 3) to holder 10. As best`shown in FIGURE 3, bag 34, which may be of a thermoplastic material suchas polyethylene or polypropylene, for example, is secured to holder byturning the edges 35 of the bag over arms 24, 2S and 26 and punchingpins 33 through the turned-over edges. As best shown in FIGURE 3, holder10 preferably is mounted on a wall, door or the like at a height suchthat the bottom of bag 34 is permitted to rest against the ground or afloor 36. This may not be necessary where small bags 34 are beingemployed, however, or where the bag has walls of sufiicient thicknessthat the bag can be adequately supported by holder 10 alone when full ofrefuse.

In using a -collapsible holder embodying this invention, a bag 34 issecured thereto in the manner previously noted, and the bag holdernormally is in the collapsed position shown in FIGURE 4 to preventodours from escaping from the bag. When it is desired to add refuse tothe bag, or to remove the bag from the holder, lid 18 is opened bylifting up tab 23, and arm 25 is pulled away from wall to open theholder. To this end a small handle may be mounted on arm at a positionwhich is below tab 23 when lid 1S is in the closed position. In order toclose holder 10, arm 25 is pushed towards support 12 until the frame iscompletely collapsed. Lid 18 then is pivoted downwardly over thecollapsed frame in such a manner that arm 25 and collapsed arms 24 and26 are positioned in channel 19 and are held therein by wall 20 of lid18 which bears against arm 25.

It is important to note that when frame 11 is collapsed the widththereof is no greater than the width of the frame in the fully openedposition. Furthermore, the collapsing of arms Z4 towards each otherfor-ces the side walls of bag 34 to collapse inwardly towards each otherthereby providing four thicknesses of wall material at the top of bag 34when the bag is closed. In addition, the side walls of bag 34 aredirectly supported by the eXtensions of hinge pins 31.

While preferred embodiments of this invention have been disclosedherein, those skilled in the art will appreciate that changes andmodifications may be made therein without departing from the spirit andscope of this invention as defined in the appended claims.
